Description

Description Raising seedling pot for root vegetables

The present invention can obtain a desired growth state and solve environmental pollution problems by adding non-wood fiber as a main material and adding a sub-material having an effect according to the purpose of growing seedlings. It relates to a seedling raising pot.

Background art

As a well-known conventional nursery pot, a pot formed by molding a synthetic resin sheet such as vinyl chloride into a small flowerpot shape is most often used. Although this seedling pot made of a synthetic resin sheet is inexpensive, it takes time and effort to remove the seedling pot when it is replaced in a field or a pot. However, this method not only hinders the growth after the main planting, but also has the drawback that when the seedling pots that are no longer needed are incinerated, environmental pollution and pollution problems occur. In order to solve this drawback, paper-like seedling pots that use waste materials generated in the fields of agriculture and forestry instead of synthetic resin sheets have been proposed and are being used.

However, conventional paper-growing pots made of such raw materials are economical due to the use of waste materials, and are biodegradable even if left in the soil after use because they are natural materials. Therefore, although the disadvantages of the synthetic resin sheet seedling pots have been eliminated, the expected effects are only the aforementioned economic effects and environmental issues. The effect on the growth of the body is not considered at all, and the requirements for the plant, such as the nature of the seedling to be planted, whether it is root vegetable, fruit vegetable or leafy vegetable, are not considered at all. There was a problem to be solved, which is that no fostering is expected. Therefore, there has been a strong demand for the development of seedling pots that take into account not only the economic effects and environmental issues but also the requirements for the plants to be planted.

Disclosure of the invention

Accordingly, an object of the present invention is to raise seedlings of crops that are commonly known as root vegetables. In order to solve the above problems, mass production is carried out using inexpensive plant materials and unused materials, such as radish, potato, burdock, yurine, etc. Focusing on the growth of tubers, etc., the product price is low, it is tough and safe and harmless. An object of the present invention is to provide a seedling pot that does not need to be used.

According to the present invention, a bamboo fiber that has not been boiled, a boiled fiber material obtained by boiling a legume plant such as a grass or a legume, and a carbonized material obtained by roasting a non-wood plant material and performing charcoal treatment. Provides root growing seedling pots made by molding a mixed material consisting of plant material and a small amount of urea. For root crops formed by molding a mixed material consisting of a boiled fiber material, a carbonized plant material obtained by roasting a non-wood plant material and carbonized, and a small amount of urea and a powder whose main component is silicon dioxide. Provide nursery pots.

In a preferred embodiment, the plant material used is about 7% by weight of fibers obtained from antibacterial bamboo stems, stems, skins, cores and the like. /. About 10% by weight, about 50% by weight to 60% by weight of reed or goat fiber as a boiling fiber material, and descendant husk, tea husk, oil residue, coffee residue as a carbonized plant material (already roasted) (It is not necessary to bake again.) Baking (roasting) etc. Mix about 20% to 30% by weight of carbonized, and mix with about 15% by weight of urea. It is a mixed material for molding. The mixed material thus obtained is formed at a molding temperature of 180 ° C or more, around 200 ° C, and a molding pressure of 3 to 6

Molding time 24 3 3 Mold under the condition of OS ec. In this case, the fibers bond to each other by hydrogen bonding without adding a binder corresponding to the sizing agent in the paper, and the desired shape as a pot is maintained. As a method for molding the seedling raising pot, as described above, the bamboo fiber, the boiling fiber material, and the carbonized plant material may be directly pressurized and heated in a mold having a predetermined shape. Needless to say, it may be used as a means for suspending to make a slurry, making paper using a sieving net, and pressing. As described above, the bamboo fiber in the material has antibacterial properties, so that the growth of the side roots of the planted seedlings is suppressed as they approach the side wall of the pot, and the nutrients are accumulated in the main roots and the main roots are concentrated. It has the effect of making it excellent as a root vegetable.

Also, since it is biodegraded in the soil, it can be replaced with a conventional synthetic resin sheet. As it does not need to be removed as in the case of plants, it can save the time of replanting, and at the time of biodegradation, the carbon of carbonized plant material reacts with urea to produce nitrogen, which is used as fertilizer.

By mixing the above materials with 2-5% by weight of diacid silicon (Si ₂ ), that is, mainly powdered stone, continuous planting of the same species is possible. In general, it has been pointed out that spoilage of soil moisture by Fusarium fungus is a factor that inhibits continuous cropping.However, mixed silicon dioxide powder causes water in the soil to vibrate, causing water spoilage. It acts to prevent and eliminate factors that inhibit continuous cropping.

The molded seedling raising pot is provided with a drainage hole 1 on the bottom surface, a projecting portion 3 for preventing the drainage hole 1 from being closed, and a vacant groove 4 similarly to the flowerpot. Such a nursery pot decomposes in about two months by biodegradation when buried in the soil and left to stand. This period corresponds to the period until the roots of the planted seedlings grow and the seedling pots buried in the soil begin to inhibit root growth of the seedlings. Needless to say, this period varies depending on the plant, but if small through-holes 2 are drilled in the bottom or side wall for the purpose of coping with this, the small through-holes 2 become tight and biodegradation occurs. It will be faster. The number of small through holes 2 is usually 1 or more and about 1 to 2. Also, if about 2% of a water repellent is mixed into the above-mentioned mixed material for molding, biodegradation can be delayed for several months. The seedling pot containing this water repellent has a long life in the soil, and is useful for bulb cultivation and grafting.

The seedling pot for root crops of the present invention has a water adjusting power over a wide range of 7% to 25%, adsorbs water vapor when the humidity in the surrounding air is high, reduces the humidity, and adsorbs when the humidity is low. It has the function of automatically adjusting the humidity to an appropriate level by releasing water vapor. Therefore, when used as a seedling pot, it can withstand temporary drying of the outside air. Furthermore, it is more suitable for use in cold climates because of its excellent heat retention (18 ° C to 10 ° C) as compared to a vilusheet pot.

Since raw materials are discarded instead of being used, it is possible to reduce material costs and reduce manufacturing costs. In addition, even when disposed of after use, low-temperature incineration is possible, so there is no damage to the incinerator and no generation of dioxin. Furthermore, even when buried in the soil as it is, bacteria It is biodegraded by element and turned into fertilizer, which contributes to soil improvement and contributes to environmental sanitation.
